To al whom '15l 'may concern.

Beit lknownl that l, HENRY M. SOMER- 'viniiii,`fafcitizen of the United States, re-

.wire suspensioncla'inp and has for its primary object vto provide a device of this ycharacter particularly designed Y for use uponelectric-power lines in cases where the conducting `vvireexerts an upward strain or pull upon the clamp.

The invention has for a 'further and more pii-rticularobject to provide a clamp of the above' typeincluding a body-member provided withl` an integral wire .engaging jaw rwextensioii having a curved lip, Vsaid body ldate being provided with* longitudinally @standing arms on opposite sides of said jam'vvhereby the clamp may be connected between two series ofinsulators, and a wire clamping plate or jawlmounted upon said body plate for clamping engagement upon the wire. f I

It is a further general object of the invention to provide a clamping device for suspended-'conducting wires, which will effectively' resistfupward or downward strains of the wire thereon, said clamp, 'as a whole, being simple in its construction and capable of manufacture at comparatively lsmall cost.

With the above and other objects in view, my invention {consists'in the novel features of construction, combination, and arrange-v nient of' parts to be hereinafter more fully described, claimed, and illustrated 'in the accompanying drawing, in which, t

Figure 1 is an elevation of a supporting structure suoli as is commonly used upon electric power lines, showing a conducting wire suspended therefr in by means of my improved clamp; Fig. 2 `s an enlarged eicvation of the clamp; and Fig, 3 is an edge view thereof. A u Referring iii detail to the drawing, o designates spaced horizontal beams which are fixed upon one or more verticai uprights 6. The electric conducting wire, in; dicated at 7, extends between the beams o and is suspended therefrom.l For 'this pui pose, a series of connected insulators 8 are Specification 'cfiLettersPatent wrnrisusrnivsioii CLAMP.

suitably attached to the upper beam 5. rlhe wire suspension clamp embodies a cast in etal` plate, indicated at 9, which is provided upon its central portion with anA integral laterally extending jaw l() which projects from one side of the ybody plate. This )aw 10, at its point of juncture with the plate 9, is provided in its bottom face `with a groove or seat, indicated at ll, to

receive the conducting wire 7. lt will be observed that the central portion of the plate 9 is of greatest width, and-said plate, from each side of said central portion, is gradually reduced in width or attenuated to produce the longitudinally projectingarms l2. The jaw 10 is relatively narrow and projects laterally from the body plate o centrally of its widest portion.. lllpon this face of the plateand at each sideof the jaw lG, the curved or arcuate concave-convex lips 13 are integrally formed, the concave faces of said lips being downwardly disposed. These lips, in effect, provide con tinuationsof the wire receiving channel or groovev l1 in thebottoin faceof the jaw l0 and the conducting wire extends upwardly upon said curved lips from each'side of said iavv. l

le designatesthe movable Wire clamping jaw provided with'the wire receiving seat l5 and a curved terminal lip l@ which is adapted to be engaged through an opening formed inthe body' plate 9 of the clamp. The jaws l0 and le are provided with opon- -ings to receive the clamping bolt l? upon the laterally extending flanges 20 which are formed upon their llongitudinal. 4 edges.

lt will be understood that, after the upwardly projecting arm l2 of the clamp has been attached to the hook of the lower one of the series of insulators 8, the conducting wire T is securely clamped between the "ews l0 and li. llie downwardly entending arm l2 of the clamp is connected to the upper end of a second series of insulators, A indicated at 2l, the lower insulator in said' series being suitably attached to .he lower beam 5 of the supporting structure. As above stated, the conducting wire ei/tends on an upward inclination from the center of the cliip and upon the curved lips i3. It will be apparent that, when the 'Wire liti@ clamp has been arranged between -the two 'series of insulators 8 and 2,1 and the wire securedtherein 4in the manner above stated,

said wire will be heldin place with res ect to the supporting structure and upwar or downward pull's or strains resisted ,by the -clamping device, wherein the wire lis held'.

It isl obviousp of course, that, if desired, the

lower series of insulators 21. may be eliminated when it is not possible .or convenient toem loy the lower beam or bar 5, anda suitab e weight connected to thelower arm of the clamp,'or said arm'tied down to any convenient fixed or stationary object. It will thus be 'manifest that I havel devised a very'simple form ofclamping device which will not only hold the wire against downward movement when suspended in the supporting structure, but also afford means for ing ]aw plate may also be considerably modified. "Ihe form and proportion of the several structural features of the clamp body can also be greatly varied in order to adapt the clamp to certain conditions, and I, therefore, reserve the privilege of resorting to vter described including a mg and arrangement of the movable clamp' 'all such legitimatel modificationsv as be of the invention as claimed.

yHaving thus full-y described my invention, what I desire toclaim and secure by Letters Patent isz- 1. A wireV suspension clam of the characboy Plate having a relatively wide medial portion and oppositely projecting, relatively narrow, longitudinally extending arms terminating in loops or eyes, and wire clamping -means on one side of'the central portion of the body plate.

2; A wire suspension clamp of the character described including a body plate having a relatively wide medial portion provided upon one side and at the center thereof with a laterally projecting jaw and also with longitudinally curved wire receivinv. lipsl ex-' tending from the opposite edges ci: the jaw to the outer edges of .the body plate, a movl airly embodied within the spirit and 'scope able wire clamping 'jaw mounted at one oi' its ends in said body plate and opposed -to said stationary jaw, and relatively narrow, longitudinally projectingy 'arms integrally formed with 'the body plate and extending in opposite directions withy respect to the center thereof, and said arms termir nating in attaching loops.

In testimony whereof I. hereunto `aiix my signature in the presence of two witnesses.
